The German playmaker issued an apology to Gunners fans on his Facebook page after he made a hash of his early spot kick against the European Champions.

It was a mistake that proved costly as Bayern hit back following Wojciech Szczesny’s later sending off to secure a 2-0 first-leg win – despite missing their own penalty after the Polish stopper brought down Arjen Robben.

Despite his recent struggles the midfielder remains a key member of Wenger’s side, and the Frenchman has called for a positive response from the German international after his latest slip-up.

"Is he over it now? Certainly not, because 48 hours is a short time to get over that, but it is also part of the job as to deal with disappointment and to show that you can respond to it," the Arsenal manager said ahead of Saturday's Premier League clash against Sunderland.

"He apologised after the game, but I don't think people are shocked by the fact that he missed a penalty because Bayern missed a penalty as well.

"He takes his penalties in an unusual way so people are maybe a little bit less understanding, but everybody can miss penalties. It is his way, you accept it or not. It's his way of taking penalties like that."

However, Ozil isn't the first Arsenal man to lose his head from the spot, and asked whether he would let the 25-year-old take a penalty again, Wenger said: "I believe that at the moment you have to let him recover from that.

"I had examples before, with people like Dennis Bergkamp who missed an important penalty in 1999 and refused after to take any penalty [for a while].

"Incidentally he [Bergkamp] gets a statue [at the Emirates Stadium] on Saturday, so that doesn't take a statue away from you and some other people don't mind and [take penalties] again.
